Maybe you’re unaccustomed to having to use your hands for anything these days seeing as how you live in your modern apartment on the waterfront with stainless steel appliances, a trash compactor and a garbage disposal. So I guess when the horrifying prospect of having to reach into the sink drain comes up (obviously after you’ve been doing some Patrick Bateman shit and shoving limbs down it), you’re slightly reluctant to do so with a bare hand.
And so, like a little bitch, you put on a glove so that you can reach into the recesses of this hole without actually having to feel anything. My guess is this is probably how you finger a woman too. Maybe next time you clog that shit, you can find it within the depths of your guts to muster the courage to place your bare hand in there like someone with a dick would.
